/**
 | 
			
		||||
 * Pure-PHP implementation of AES.
 | 
			
		||||
 *
 | 
			
		||||
 * Uses mcrypt, if available/possible, and an internal implementation, otherwise.
 | 
			
		||||
 *
 | 
			
		||||
 * PHP versions 4 and 5
 | 
			
		||||
 *
 | 
			
		||||
 * NOTE: Since AES.php is (for compatibility and phpseclib-historical reasons) virtually
 | 
			
		||||
 * just a wrapper to Rijndael.php you may consider using Rijndael.php instead of
 | 
			
		||||
 * to save one include_once().
 | 
			
		||||
 *
 | 
			
		||||
 * If {@link self::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
 | 
			
		||||
 * {@link self::setKey() setKey()}.  ie. if the key is 128-bits, the key length will be 128-bits.  If it's 136-bits
 | 
			
		||||
 * it'll be null-padded to 192-bits and 192 bits will be the key length until {@link self::setKey() setKey()}
 | 
			
		||||
 * is called, again, at which point, it'll be recalculated.
 | 
			
		||||
 *
 | 
			
		||||
 * Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't
 | 
			
		||||
 * make a whole lot of sense.  {@link self::setBlockLength() setBlockLength()}, for instance.  Calling that function,
 | 
			
		||||
 * however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
 | 
			
		||||
 *
 | 
			
		||||
 * Here's a short example of how to use this library:
 | 
			
		||||
 * <code>
 | 
			
		||||
 * <?php
 | 
			
		||||
 *    include 'Crypt/AES.php';
 | 
			
		||||
 *
 | 
			
		||||
 *    $aes = new Crypt_AES();
 | 
			
		||||
 *
 | 
			
		||||
 *    $aes->setKey('abcdefghijklmnop');
 | 
			
		||||
 *
 | 
			
		||||
 *    $size = 10 * 1024;
 | 
			
		||||
 *    $plaintext = '';
 | 
			
		||||
 *    for ($i = 0; $i < $size; $i++) {
 | 
			
		||||
 *        $plaintext.= 'a';
 | 
			
		||||
 *    }
 | 
			
		||||
 *
 | 
			
		||||
 *    echo $aes->decrypt($aes->encrypt($plaintext));
 | 
			
		||||
 * ?>

		||||

/**
 |

 * Pure-PHP implementation of RC4.
 | 
			
		||||
 *
 | 
			
		||||
 * Uses mcrypt, if available, and an internal implementation, otherwise.
 | 
			
		||||
 *
 | 
			
		||||
 * PHP versions 4 and 5
 | 
			
		||||
 *
 | 
			
		||||
 * Useful resources are as follows:
 | 
			
		||||
 *
 | 
			
		||||
 *  - {@link http://www.mozilla.org/projects/security/pki/nss/draft-kaukonen-cipher-arcfour-03.txt ARCFOUR Algorithm}
 | 
			
		||||
 *  - {@link http://en.wikipedia.org/wiki/RC4 - Wikipedia: RC4}
 | 
			
		||||
 *
 | 
			
		||||
 * RC4 is also known as ARCFOUR or ARC4.  The reason is elaborated upon at Wikipedia.  This class is named RC4 and not
 | 
			
		||||
 * ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1 specification.
 | 
			
		||||
 *
 | 
			
		||||
 * Here's a short example of how to use this library:
 | 
			
		||||
 * <code>
 | 
			
		||||
 * <?php
 | 
			
		||||
 *    include 'Crypt/RC4.php';
 | 
			
		||||
 *
 | 
			
		||||
 *    $rc4 = new Crypt_RC4();
 | 
			
		||||
 *
 | 
			
		||||
 *    $rc4->setKey('abcdefgh');
 | 
			
		||||
 *
 | 
			
		||||
 *    $size = 10 * 1024;
 | 
			
		||||
 *    $plaintext = '';
 | 
			
		||||
 *    for ($i = 0; $i < $size; $i++) {
 | 
			
		||||
 *        $plaintext.= 'a';
 | 
			
		||||
 *    }
 | 
			
		||||
 *
 | 
			
		||||
 *    echo $rc4->decrypt($rc4->encrypt($plaintext));
 | 
			
		||||
 * ?>
 | 
			
		||||
